FIG. 1 shows a pair of heat insulating materials in which a bright surface film 10 and a spacer 20 are combined. The bright surface film 10 is, for example, a polyimide film with a thickness of 25 μm and an aluminum vapor-deposited film of 80 OA−2 on both sides, and the spacer 20 is also made of a polyimide film with a thickness of 25 μm.

The embossing process shown in Figure t was performed. FIG. 3 shows a sectional view taken along line XX in FIG.
Spacers 20 are arranged and supported at certain intervals on O. The bright surface film 10 and the spacer 20 are supported by fixing several points of each n contact surface with, for example, double-sided adhesive tape or an adhesive. In FIG. 4, a pair of heat insulating materials are placed on the outer surface of a low-temperature pipe 30, which is an inner container to be insulated, within a pipe 40 that is vacuum isolated from the atmosphere.

The heat insulation performance of has the characteristics shown by the curve Cc in the graph of the number of bright surface films and the amount of heat penetration per unit area q (W/j) shown in Figure 5, and the side shoulder part B of the non-contact bright surface film The heat insulation performance has a characteristic represented by a straight line DIc. The heat insulation performance of the laminated portion B becomes superior to that of the laminated portion A as the number of bright surface films increases. Therefore, a laminated heat insulating material having a structure in which the laminated part and the laminated part B are made of coarse metal exhibits a heat insulation performance that is equal to the eIC of each metal part area. Furthermore, the heat insulating material of the laminated portion B is lightweight because it does not include a spacer.

The heat transfer distance is longer than that in Figure $4, and it exhibits insulation performance with q smaller than the insulation performance of curve C shown in Figure 5.

The i portion exhibits linear characteristics. Moreover, since the spacers 2] are present in a lattice shape, the bright surface film 1G extending between the spacers has little sagging, and can be further prevented from coming into contact with the bright surface films 10 of the upper and lower layers in a laminated state. Therefore, although the area occupied by the spacer 21 is large,
The heat insulating performance of the laminated heat insulating material is the same as in the case shown in FIG. 4, and the rigidity of the laminated heat insulating material can be increased.

。The difference between FIG. 8 and the above embodiment is that the bright surface film 1
The spacer 22 disposed on the 0 is composed of a plurality of pairs of a bright surface film 22b and a spacer 22a! *This is due to the fact that it is layered. FIG. 9 shows a state in which the present heat insulating material is wound around the low temperature pipe 30 in a roll, similar to FIG. 4. According to this embodiment, the heat insulation performance of the laminated portion of the bright surface film 10, the spacer 22a, and the bright surface film 22b is the curve C in FIG.
, the number of bright area films is 10 and 2.
Compared to the case shown in Fig. 4, the number of films in the bright area is tripled, and the heat insulation performance is excellent. It becomes something. Therefore, the bright surface film does not impair the straightness characteristic, that is, does not include the spacer 22]
The increased distance between the films at the facing portions of O has the effect of further improving the heat insulation performance of the laminated heat insulating body while preventing the bright surface films 10 from coming into contact with each other and ensuring straightness characteristics.

Between the laminated parts and the insulation that maintains the rigidity of the entire body? The bright surface films 10 face each other in a non-intrusive manner without intervening the cosplayer 22. Since the NM part B and the NM part B can coexist, the heat infiltration edge in the laminated part B can be made smaller than that in the laminated part, which has the effect of improving the heat insulation performance of the +11 layered heat insulating body. For example, 15 pieces of bright part film of mm part A and 3 pieces of bright part film of 8 parts are wrapped in a low temperature pipe with an outer diameter of 42 m and a length of 1.5 m, and the laminated parts A and B are wrapped at a width ratio of 1: Winding with 10, vacuum degree] × 10 ``0r'', inside vacuum 41, H normal m,
When the insulation performance is actually measured between 77K (low-temperature pipe internal temperature), when the entire length is taken as the laminated part A, the heat loss per unit area is reduced to about /3 compared to t.

The number of spacers 22a and bright surface films 22b placed on the top of the spacer 22a and the bright surface film 22b are stacked differently in the stacking direction, that is, the number closer to the low-temperature pipe 30 on the low-temperature side is larger, and the number closer to the pipe 40 at room temperature is stacked. On the other hand, the number of layers is reduced, and spacers 23 are attached to the outermost layer along the entire longitudinal direction. That is, in this example, attention is paid to the fact that in the laminated heat insulating body, radiation heat transfer is dominated in the room temperature side, and conduction heat transfer is dominated in the low temperature side. On the side, the number of laminated sheets of the spacer 22a and the bright surface film 22b is increased, and the effect of improving the heat insulation property with the same number of laminated sheets, and the rigid spacer 23 on the outermost layer are used to improve the overall IC. This has the effect of increasing the rigidity of the laminated insulation.

This has the effect of increasing performance.
